A Beginner’s Guide to Begonias: Hybridization and the Gateway to a New World in Its Breeding

Begonia spp. is one of the most diverse and popular ornamental plant groups, with over 2,000 species and hybrids valued for their foliage, flowers, and adaptability. Florida’s climate and horticultural industry make it a center for begonia production, yet practical guidance on hybridization remains limited. This publication provides a clear, step-by-step introduction to hybrid breeding for horticultural professionals, advanced gardeners, and researchers. Topics include basic genetics, selecting parent plants for desirable traits, pollination techniques to control crosses, and potential challenges. Methods for seed collection, germination, and hybrid evaluation are outlined with emphasis on assessing ornamental quality and stress resistance. Case studies from UF/IFAS breeding programs highlight successful crosses. This guide bridges science and practice to advance Begonia breeding for Florida and beyond.
